Ok, so if dope can be detected from a DNA test on hair, then y r scientists spending so long trying to develop cloning? Y not give the subject a few spliffs? Canna stays in the system 4 about 28 days, & is only detectable thro blood & piss samples. I agree that it is stoopid to smoke & play, drive, operate machinery, have sex etc, but making up **** about DNA testing 4 dope is like Foxy going on Brasseye & telling us that paedo's have more in common with crabs than real humans on a genetic level.
Come on guys, get a grip!!!
